This article reviews 14 multivariate theories of experimental substance use (e.g., alcohol and marijuana use) among adolescents, including those theories that emphasize (a) substance-specific cognitions, (b) social learning processes, (c) commitment to conventional values and attachment to families, and (d) intrapersonal processes. Important similarities and differences among these theories are addressed, as are the conceptual boundaries of each theory. In an attempt to integrate existing theories, a framework is proposed that organizes their central constructs into 3 distinct types of influence (viz., social, attitudinal, and intrapersonal) and 3 distinct levels of influence (viz., proximal, distal, and ultimate). Implications for future theory development are discussed.

A new meta-analysis of research on hostility and physical health was conducted that includes 15 studies used in previous meta-analytic reviews and 30 new independent studies. Overall, the results suggest that hostility is an independent risk factor for coronary heart disease (CHD). For structured interview indicators of potential for hostility, the weighted mean r was .18. After controlling for other risk factors for CHD, the widely used Cook-Medley Hostility Scale and other cognitive-experiential measures were most predictive of all-cause mortality (weighted mean r = .16) and, to a lesser extent, CHD (weighted mean r = .08). Similar to other areas of research, the increased use of high-risk studies in recent years produced an increase in null findings.

Using the Center for Epidemiologic Studies of Depression scale, 25.6% of the 2,823 subjects reported high symptom levels. Rates among women (31.9%) and particularly men (17.3%) were higher than has been typically reported for older Mexican Americans and older adults in general. Consistent with previous studies of older adults, gender, lack of insurance, financial strain, chronic health conditions, and disability were found to be associated with depressive symptoms. Several cultural factors were also associated with increased risk, including immigrant status, levels of acculturation and assimilation, health locus of control, and recency of immigration. An interaction between gender and immigrant status was found such that, in relation to subjects born in the United States, female immigrants were at significantly higher risk for depressive symptoms, whereas male immigrants were at lower risk.

This paper reviews findings from 58 prospective studies of illicit substance use (ISU) among adolescents. It arranges 384 findings according to three types of influence (viz., social, attitudinal, and intrapersonal) and four levels of influence (viz., ultimate, distal, proximal, and immediate). The bulk of evidence reconfirms the importance of several predictors of ISU (e.g., intentions and prior substance-related behavior, friendship patterns and peer behaviors, absence of supportive parents, psychological temperament), reveals that a few variables thought to be well-established predictors may not be (e.g., parental behaviors, parental permissiveness, depression, low self-esteem), and uncovers several variables where findings were either sparse or inconsistent (e.g., the role of public policies concerning ISU, mass media depictions of ISU, certain parenting styles, affective states, perceptions of parental disapproval for ISU, and substance-specific refusal skills). Directions for future research are discussed.

Smokers registering for a televised cessation program who also expressed interest in joining a support group and who had a nonsmoking buddy were randomly assigned to 3 conditions: no-contact control, discussion, and social support. All Ss received a self-help manual and were encouraged to watch the daily TV program. Ss in the discussion and social support conditions were scheduled to attend 3 group meetings (one with a buddy). Social support Ss and buddies received training in support and relapse prevention. A 4th analysis group was composed of Ss who failed to attend any of the scheduled meetings (no shows). There were strong group effects at the end of treatment. Abstinence rates were highest in the social support group, followed, in order, by the discussion group, no shows, and no-contact controls. The social support group improved outcome by increasing both the level of support and program material use (reading the manual and watching TV).

The exact relation between gastro-oesophageal reflux and asthma remains poorly understood. To determine whether gastro-oesophageal reflux in asthmatics results in oesophagitis, endoscopy and oesophageal biopsy were performed on 186 consecutive adult asthmatics. The presence or absence of reflux symptoms was not used as a selection criterion for asthmatics. Endoscopy was performed by two endoscopists using predefined criteria. All asthmatics had discrete wheezing and either a previous diagnosis of asthma or

The factor structure of the Center for Epidemiological Studies-Depression Scale (CES-D) has not been well defined among elderly Mexican Americans. Although most prior research suggests the CES-D has four factors, prior research also suggests that the factor structure of the CES-D may vary with culture. In addition, previous theory and research on other depression inventories suggest only two factors: a general depression factor and a psychological well-being factor. The current study determines the number of factors for the CES-D in the Hispanic Established Populations for Epidemiologic Studies (H-EPESE) survey (N = 2,536) and in a previous study of elderly Mexican Americans living in San Antonio, Texas (N = 330). The factor analytic results argue strongly for the two-factor model, and this model is the only structure that yielded consistent results across subgroups (e.g., male vs female or Spanish vs English language of interview). We conclude that the CES-D has only two factors among elderly Mexican Americans.
